Study Notes
Liver and Bile Function
- Portal venous circulation drains nutrient-rich blood from the GI tract directly to the liver before releasing it into circulation
- Enterohepatic circulation efficiently recycles bile salts, with less than 5% loss per day
- Gallbladder has 4 parts and is responsible for storing and concentrating bile
- Neurohumoral control regulates gallbladder contractions and biliary secretion in response to nutrients
- Liver stores dietary carbohydrates and regulates glucose levels in the blood
- Liver is capable of gluconeogenesis and glycogenolysis to maintain glucose homeostasis
- The liver uses various metabolic pathways and enzymes to adjust circulating glucose levels
- Hepatocytes store triglycerides, synthesize lipoproteins, and convert cholesterol into bile salts
- Liver synthesizes and transports phospholipids and cholesterol to all body cells
- Liver plays a crucial role in fat metabolism, including the transformation and absorption of triglycerides
- Bile salts from the liver form micelles to aid in the absorption of fats in the small intestine
- Emulsification of fat droplets with bile salts facilitates the absorption of cholesterol and fats in the small intestine
